Consider the given equation is 3-2x=15 and one of the 6 in the options is -6.

Given:

The equation is

3-2x=15

To find:

The value of x.

Solution:

We have,

3-2x=15

Subtracting 3 from both sides, we get

3-2x-3=15-3

-2x=12

Divide both sides by -2.

x=\dfrac{12}{-2}

x=-6

Therefore, the value of x is -6.

Cameron is older than Hassan. Their ages are consecutive integers. Find Cameron's
Alexxandr [17]

Answer:

25

Step-by-step explanation:

So consecutive integers, just means they're separated by a value of 1. This can be generally expressed as "a, a+1" where these two values would be consecutive integers assuming "a" is an integer.

So let's express Hassan's age as the variable "x", since it's unknown. Since Cameron is older, and by definition of a consecutive integer, Cameron's can be expressed as "x+1"

So the equation we need to set up is Cameron's age + 5(Hassan's age) = 145

So we can substitute the variables we defined to express Cameron and Hassan's age: (x+1) + 5(x) = 145

Distribute the 5: x+1+5x

Add like terms: 6x+1 = 145

Subtract 1 from both sides: 6x=144

Divide both sides by 6: x=24

Since we used "x" to represent Hassan's age, Hassan's age is 24. Since we used "x+1" to represent Cameron's age, Cameron's age is "24+1" which is just 25

A density curve of all the possible ages between 0 years and 25 years is in the shape of a triangle. What is the height of the t
Bad White [126]

Answer:

Step-by-step explanation:

Note that the area under a probability density curve must be 1.

The formula for the area of a triangle is A = (1/2)(base)(height).

Here the base is 25 units.  Thus, A = 1 unit^2 = (1/2)(25 units)(height), or, after multiplying both sides of this equation by 2:

2 units^2  = ( 25 units)(height)

                             2 units^2

Then (height) = --------------------- = 0.08 unit

                            25 units

The height of the triangle is 0.08 unit.
